Prospective, multi-center, randomized, open label comparative Phase III study in patients with intermediate to high-risk (as defined in the SURVIVE trial) HER2-positive or HER2-low early breast cancer, who participate in the SURVIVE trial and experience a molecular relapse, as assessed based on a positive circulating tumor DNA (ctDNA) result, with 2:1 allocation to:
* Arm A: Trastuzumab-Deruxtecan (i.v. 5,4 mg/kg, q3w) + endocrine therapy (if hormonal-receptor-positive) for 16 cycles or until relapse, if earlier
